Re: When will filming start?

All three TF movies had a similar release date, so the start of principle photography should be identical.

Previous star of filming:

TF - April 19
ROTF - June 2
DOTM - May 18

I'm guessing May 2013. But don't forget that pre-production should star a few months earlier. For example DOTM pre-production started October 1. So we might be only 8 months away from some serious TF4 news.
